What are 2 Step Equations?
2 step equations are algebraic expressions that require two operations to solve for the unknown variable (typically denoted by "x"). The general form of a 2 step equation looks like this:
ax + b = c
where:
- a is the coefficient of the variable
- b is a constant
- c is another constant
When fractions are involved, solving these equations requires a slightly different approach. Let’s break down the process.
Step-by-Step Guide to Solving 2 Step Equations with Fractions
Step 1: Eliminate the Fraction
The first step in solving any equation with fractions is to eliminate the fraction. This can often be achieved by multiplying both sides of the equation by the least common denominator (LCD) of the fractions involved.
For example, consider the equation:
1/2 x + 1/4 = 3/4
To eliminate the fractions, the LCD here is 4. Multiplying every term by 4 gives us:
[ 4(1/2 x) + 4(1/4) = 4(3/4) ]
This simplifies to:
[ 2x + 1 = 3 ]
Step 2: Isolate the Variable
Next, you need to isolate the variable (x). To do this, you will perform inverse operations. Continuing from our example, we want to isolate the term with x:
[ 2x + 1 = 3 ]
Subtract 1 from both sides:
[ 2x = 2 ]
Step 3: Solve for x
The final step is to solve for x. Divide both sides by the coefficient of x (in this case, 2):
[ x = 1 ]
Summary of Steps
To summarize, here is a concise step-by-step breakdown:
- Eliminate the fraction by multiplying by the least common denominator.
- Isolate the variable by performing inverse operations.
- Solve for the variable by dividing or multiplying as needed.
Tips for Mastering 2 Step Equations with Fractions
-
Practice, Practice, Practice! The more equations you solve, the more comfortable you will become. Use a variety of problems that include different types of fractions.
-
Double-check your work! After solving, substitute your answer back into the original equation to verify that both sides are equal. ✔️
-
Stay organized! Write each step clearly to avoid confusion as you work through the problem.
Example Problems
Let’s go through some examples to illustrate the process:
Example 1
Solve for x in the equation:
3/5 x - 2/3 = 1/6
Step 1: Eliminate the fraction (LCD is 30):
[ 30(3/5 x) - 30(2/3) = 30(1/6) ]
This simplifies to:
[ 18x - 20 = 5 ]
Step 2: Isolate the variable:
[ 18x = 25 ]
Step 3: Solve for x:
[ x = 25/18 ]
Example 2
Solve for x in the equation:
1/4 x + 3/8 = 5/2
Step 1: Eliminate the fraction (LCD is 8):
[ 8(1/4 x) + 8(3/8) = 8(5/2) ]
This simplifies to:
[ 2x + 3 = 20 ]
Step 2: Isolate the variable:
[ 2x = 17 ]
Step 3: Solve for x:
[ x = 17/2 ]
